This image shows an integration topology that spans an Oracle Cloud region and an on-premises data center.

The Oracle Cloud region has an Oracle Cloud Infrastructure tenancy and Oracle Utilities SaaS.

Oracle Utilities SaaS has the following components:

A SaaS batch framework containing the following types of batches, which send API requests to Oracle Cloud Infrastructure Object Storage:
- Generalized data export batches
- DataConnect batches
- SQL-driven batches
A SaaS messaging framework that does the following:
- Sends outbound messages from Oracle Utilities SaaS to Oracle Integration.
- Hosts an API service that receives requests from Oracle Integration and from on-premises applications.
A URL allow list to regulate requests from Oracle Utilities SaaS to resources in Oracle Cloud Infrastructure.
The following built-in SaaS tools accessed by external users:
- Reporting using BI Publisher
- Analytics using Oracle Analytics
- SQL querying using SQL Developer Web

The Oracle Cloud Infrastructure tenancy has the following components:

Oracle Cloud Infrastructure Identity and Access Management, to authenticate and authorize communication with the resources in Oracle Cloud Infrastructure.
Oracle Identity Cloud Service, to authenticate and authorize communication from Oracle Cloud Infrastructure to Oracle Utilities SaaS.
Oracle Cloud Infrastructure Object Storage buckets, to which API requests are sent from the SaaS batch framework and from on-premises data-retrieval jobs.
Serverless Oracle Cloud Infrastructure functions invoked by events generated by Oracle Cloud Infrastructure Object Storage. These functions interact with an on-premises data warehouse or data lake and with other on-premises applications.
Oracle Integration with integration flows between the SaaS message framework, Oracle Cloud Infrastructure Object Storage, other Oracle SaaS applications, and on-premises applications.

The on-premises data center has the following components:

A data warehouse or data lake, to which data is loaded by using data-retrieval jobs that fetch data from Oracle Cloud Infrastructure Object Storage and using data staged by the serverless functions deployed in Oracle Cloud Infrastructure.
Other applications that interact with the serverless functions in Oracle Cloud Infrastructure and with Oracle Integration.
